discord-bot: resolve Rob's Syncro scope contradiction — full billing access

Rob's CAN list granted full Syncro "same as any tech" (incl. bill time +
create invoices), but the CANNOT list forbade billing actions (add line
items, create invoices, update ticket status) — a direct conflict that left
the bot's behavior on Rob's billing requests undefined. Per Mike, Rob gets
full Syncro including billing; remove the contradicting CANNOT line. Restarted bot.
